An air cylinder of a pneumatic sealing system is connected with a tooling, one end of the air cylinder is connected with a pneumatic piston rod, the pneumatic piston rod and a piston tube head connecting piece are fixedly connected by bolts, and an air source of the air cylinder is provided by a compressed air source; both sides of the piston tube head connecting piece in a hot water system are respectively connected with a hot water tube joint, and one end of the hot water tube joints is connected with a hot water tank; and tube opening positions at the other ends are respectively connected with a first tubular elastic sealing piece and a second tubular elastic sealing piece. The pneumatic piston rod is arranged on the vertical bisecting line of the center connecting line of the tube openings of the two hot water tubes, thereby ensuring the stress balance and the parallel advance and retreat of the piston tube head connecting piece and achieving an ideal sealing effect. The invention has simple structure, convenient operation, good pressure test leak-detecting effect and high efficiency.
Description
Technical field
The present invention relates to the hot water pressure test leak-detecting device that a kind of heat interchanger carries out in manufacture process.Can be used for the hot water leak detection test of air conditioning for automobiles heat interchanger.
Background technology
Before dispatching from the factory, heat interchanger must carry out the hot water leak test, to guarantee the heat interchanger product quality and not produce leakage in actual use.But heat interchanger manufacturer leak hunting method generally adopts manual detection at present, single, manual operation, the hot water that will have certain pressure is input to heat exchanger tube, the test of manually hunting leak, because air-proof condition is simple and crude, the variation at any time of pressure in the pressure testing process, make test result inaccurate, not only production efficiency is low, cost is high, and product quality is difficult to guarantee that heat interchanger hot water leakage phenomenon happens occasionally.For adapting to developing rapidly of auto manufacturing, be badly in need of a kind of mechanization, standardized heat interchanger hot water pressure test leak-detecting equipment.
Summary of the invention
For overcoming above-mentioned shortcoming, the invention discloses a kind of hot water pressure test leak-detecting device of heat exchanger.Apparatus of the present invention adopt mechanization fully, require to carry out according to leak detection, not only save time, good leak tightness between laborsaving but also pressure test leak-detecting device and the heat interchanger, pressure be up to standard, makes that detecting quality improves greatly.
A kind of hot water pressure test leak-detecting device of heat exchanger comprises pneumostop system and hot-water heating system, it is characterized in that:
1) described pneumostop system: cylinder is connected with frock, is connected with pneumatic piston rod in the cylinder, and pneumatic piston rod and piston tube head connecting piece are affixed by bolt, and the cylinder source of the gas is provided by compressed air source;
2) described hot-water heating system: piston tube head connecting piece both sides respectively are connected with a pipe joint of hot water, and pipe joint of hot water one end is connected with boiler, and the mouth of pipe place of the other end is connected with the first tubulose elastic sealing element and the second tubulose elastic sealing element respectively.
Described pneumatic piston rod is arranged on the perpendicular bisector of two hot-water line mouth of pipe lines of centres, and to guarantee piston tube head connecting piece stress balance, parallel advance and retreat reach desirable sealing effectiveness.
Described piston tube head connecting piece is connected with two pipe joint of hot water, is perforate on the piston tube head connecting piece, and hot-water line passes this hole, and realization is docked with interface of hot water.
During detection, pneumatic piston rod drives plug tube head connecting piece parallel propelling under the promotion of cylinder gas, realizes and the docking of interface of hot water thereby drive two pipe joint of hot water.
The present invention is owing to adopted two-layer elasticity tubulose elastic sealing element preferably at the hot-water line interface, the sealing joint that makes tested heat interchanger water inlet be connected with the hot water line improves greatly, thereby the pressure equilibrium that has guaranteed the test overall process is stable, do not produce escape of liquid, solve heat interchanger and docked difficult problem with test macro, greatly improved test mass.
The present invention is simple in structure, and is easy to operate, and pressure test leak-detecting is accurate, and the production efficiency height frees heat interchanger hot water pressure test leak-detecting from manual detection, and can form the automatic modernized mechanized equipment that detects of many whiles.
